pulzelli Posted May 19, 2010 Share Posted May 19, 2010 hi all , after buying a xt125r and being a bit disapointed with the general performance , ok so 125s are low on power but this felt strangled to death !!!!!!!!!!!!!!! so when up at sheffield motorcycle centre i saw a full arrow exhaust system for £220.00 i thaught why not , had it fitted so as not to effect waranty , bike was better but only marginally , anyway after talking to steve the service manager it was decided to renew carb under waranty as it was very hard to start from new and tickover was very irratic and it was definatly a bad carb , it was also dyno tested and rejeted from 105 to 110 jet, well what a difference , revs to the moon and now goes very very well , ok its still only a 125 but i now have all the power in the little engine and it gets to 65 mph very quickly [for a 125] hope this could help anyone else with this type of machine .ps it sounds great to !!!!!!!!!!!!!!!!!
